Blank and packaging for pack of pots with connection/deformation sections

A flat blank, for forming a packaging for a pack of pots, the pots having a bottom wall, a side wall closed on itself, and a top closure, the pack including at least one layer of base pots, the blank being of a tubular shell type of cardboard or the like, comprising:

• side-by-side in a longitudinal direction:
• a top panel, two side panels, a base panel, a closure panel, and a securing device configured to close the erected blank on itself;
• transverse score lines, extending in a transverse direction substantially perpendicular to the longitudinal direction, for folding the panels, for erecting the blank, and for forming the packaging and the pack;
• four sets of corner post panels, each set of corner post panels extending from a transverse end of a side panel and able to be erected relative to said side panel to form an erected corner post;
• and
• longitudinal score lines for folding the panels of the sets of corner post panels, for erecting the sets of corner post panels, and for forming the erected corner posts,
• wherein the base panel comprises
• arranged one after the other in the longitudinal direction between a first longitudinal end and a second longitudinal end of the base panel:
• a first connection/deformation section,
• a receiving portion extending over a portion of the base panel, for receiving the bottom walls of the base pots, and
• a second connection/deformation section, and
• two intermediate base score lines extending in the transverse direction between the first and second connection/deformation sections and the receiving portion, so that the receiving portion is formed by a longitudinally median transverse portion of the base panel, and is bounded transversely on the base panel by the two intermediate base score lines extending in the transverse direction,
• the intermediate base score lines defining, with the longitudinal ends of the base panel, the first and second connection/deformation sections extending over the base panel on each side of the longitudinally median receiving portion of the base panel,
• the intermediate base score lines forming two deformable hinges, such that the longitudinally median receiving portion of the base panel is movable relative to the longitudinal ends of the base panel along an axis perpendicular or substantially perpendicular to the receiving portion after erection of the blank and formation of the packaging and the pack.
